Economists at Westpac and ANZ both cite those three factors that could impact the sector and even the head of Auckland's largest real estate agency is talking of the possibility of a "slight correction''.

Dominick Stephens, the Westpac economist writing in the November 15 Home Truths, gave a bearish long-term outlook due to these three factors.

"We do believe that the ban will have a bearing on house prices eventually. Next year the market will be impacted by changes to the rules around tax deductions for property investors. And if a capital gains tax is introduced, the impact on house prices will be large,'' Mr Stephens said.

The foreign buyer ban came into force in October last year.

The Government wants to stop landlords claiming tax deductions on rental property, leading to an outcry from the Property Investors' Federation.

It wants to remove a tax loophole where investors with loss-making rental properties can subsidise part of the cost of their mortgages through a reduced tax on other income, helping them to outbid owner-occupiers for properties.

In a separate tax reform move, capital gains tax has long been on the horizon. The Tax Working Group's initial recommendations were released in September.

CoreLogic said 25% of November's residential property purchases throughout New Zealand were made by multiple property owners with a mortgage.

ANZ's housing market outlook, released in early December, cited concerns about precisely the same three factors as Westpac.

"The headwinds of tax changes, tougher landlord responsibilities and the foreign buyer ban are finely balanced with very low mortgage rates, improving credit availability, and still-strong population growth. All up we see the housing market remaining contained,'' it said, referring to loan to value restrictions.

The Auckland housing market was "behaving itself but history warns against ever ruling out a second wind'', ANZ noted.

Peter Thompson, Barfoot & Thompson managing director, reckons Auckland prices will be much the same in 2018 but is also somewhat bearish in his outlook.

"There is a chance we could see a slight market correction, as it is becoming more of a buyers' market rather than a sellers' market compared to this time last year. Days on market is lengthening and more sales are conditional on attaining finance from their banks,'' Mr Thompson, whose business sells more than 40 per cent of Auckland homes, said.

Open home numbers dropped around November "but indications are that those attending have done their homework and are interested in buying. However, with a strong economy still in demand, interest rates remaining low, building consents slowly increasing and development of new apartment blocks and new projects coming on to the market, choice is the word at this time,'' he said.

In an economic report in late November, ASB said New Zealand residential property price movements tend to broadly track those in Australia. Australian house prices are about 3% off their October 2017 peak.

Yet Sydney prices are more than 7% below the June 2017 peaks, while Melbourne prices are about 5% lower, ASB said.

"Given the falls evident in Australia, the concern is that similar weakness could be evident across this side of the Tasman and that overall NZ house prices fall,'' ASB noted.

But New Zealand house prices are still going up, albeit modestly, even though there have been modest falls in Auckland house prices since the start of the year, ASB noted.

The Reserve Bank appears far less concerned about our housing market now than it has been in recent years. Although house prices remain high compared to incomes and rents, escalation has waned since early 2017, it says.

Credit growth to households has returned to more sustainable levels.

Banks are also more rigorously assessing customers' ability to service their loans. This means a gradual reduction in the risks which the LVR restrictions were designed to mitigate. And housing market pressures are expected to remain subdued, which will further reduce risks over time, the Reserve Bank says.

Comments

This 'correction' in the market is not going to be that big of a change when most of the fundamentals restricting supply and fuelling demand are unchanged. Even if there is a move, we were all telling National for nine years it was a crisis they refused to acknowledge. Now it looks like a crisis that our Labour led government is starting to solve. Nice work.

As for the Property Investor's Federation being upset; surely this can only be a good thing. Their privileged position in our country can be highlighted by the contrast between two housing scenarios. Firstly a landlord's ability to offset taxes on unrelated wages with what would be personal costs if they didn't otherwise own a rental. Compare that with the second housing scenario where WINZ insists that extortionately high emergency housing costs for otherwise homeless families, (paid to private investors) constitutes a loan that must be repaid.
